Thanks for your work, Harald.

So, as I mentioned in another follow-up, we didn't really establish any
'ground rules' for when we're going to re-tag the builds into Rawhide.
Aside from the questions other groups may have, from the QA side, I'd
suggest we want at least:

* two or three successful tests of the yum process with an existing
Rawhide install

* a successful test of a fresh install with the /usr move packages
(assuming we're in a state where we can even do a fresh install
*without* the /usr move stuff: we will know more on that front shortly)

and ideally:

* a successful test of a media-based upgrade from F16

before we go ahead and PULL SOME LEVERS.

I have the /usr move feature on the agenda for the QA meeting on Monday
morning, so we'll plan the testing out in more detail then. I guess
we'll look at building a special install image for testing, if that's
necessary. If you and/or kay could be at the meeting - 1600 UTC on
Monday - that'd be a big help. Thanks!
